Good Practices

Engage facade specialist especially for propriotary systems which require in-house design and instllation of anchorages and supports (with warranty).

Opting for a thicker gauge material enhances rigidity and strength, helping to reduce movement after installation and minimizing the effects of oil canning. Additionally, selecting narrower panel widths can decrease the visibility of oil canning, as smaller gaps between panels can reduce its appearance. Using supporting products, such as stop ends on interlocking panels, can further help in reducing the risk of oil canning. Choosing a matte, low-gloss finish can reduce reflectivity, making oil canning less noticeable. A textured finish may also help to diminish the visibility of waves and distortions.

Proper handling and storage are critical factors that should be managed throughout production, transportation, and installation to prevent damage or warping of the materials.

Using fasteners and clips that allow panels to float and avoid thermal stresses can help minimize oil canning in metal cladding and roofing panels. Care should also be taken to prevent misalignment, over-engagement, or overtightening of fasteners, while allowing sufficient space for thermal or structural movement. Strengthening panels with fluting or beading, along with ensuring a level substructure, can improve installation quality and reduce the likelihood of oil canning.

  1. Good site practices should be adopted so that panels that are delivered to site are properly stored and protected. The storage areas should be away from activities that may cause accidental damage to the panels. Sharp tools should be kept away from storage areas.
  2. The panels should be inspected for scratches and dents before they are installed. Damaged panels should be rejected. If repairs are to be done to damaged panels, they must be examined strictly before they are allowed to be re-used.
  3. During installation of panels, gondolas and lifting devices should be properly fitted with pads and styrofoam so that they will not scratch or damage the panels.
  4. After completion of each stage of work and the protection film removed, inspections should be carried out to the installed panels.
  5. During regular repair and maintenance works, care should be taken to ensure that impacts that may scratch or damage the panels are prevented.
